It has long been stated that the mean temperature of humans is 98.6degreesF. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6degreesF. They measured the temperatures of 61 healthy adults 1 to 4 times daily for 3 days, obtaining 275 measurements. The sample data resulted in a sample mean of 98.3degreesF and a sample standard deviation of 1degreesF. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6degreesF at the alphaequals0.01 level of significance. State the hypotheses. Upper H 0: ▼ sigma p mu ▼ equals not equals less than greater than 98.6degreesF Upper H 1: ▼ sigma mu p ▼ less than not equals greater than equals 98.6degreesF Find the test statistic. t 0equals nothing (Round to two decimal places as needed.) The P-value is nothing. (Round to three decimal places as needed.) What can be concluded? A. Do not reject Upper H 0 since the P-value is less than the significance level. B. Reject Upper H 0 since the P-value is less than the significance level. C. Reject Upper H 0 since the P-value is not less than the significance level. D. Do not reject Upper H 0 since the P-value is not less than the significance level.
